the impression-cylinder to allow the succeeding sheet to pass down to be printed. It will also be obvious that the exact construction of the parallel motion shown herein for conveying the traveling grippers in a practically rectilinear path is not material to this invention, as several modifications of the construction may be made without departing from the principles of parallel motion well known in connection with other classes of machineryas, for instance, instead of slotting the upper ends of the levers D and permitting them to slide upon the rod 0', the standards I) b may be made with vertical slots in their upper ends, the upper ends of the levers D be pivoted to the rod I)", and the latter be allowed to slide vertically in the slots in the standards I) b", and a similar path thus be gotten for the traveling grippers carried by the lower ends of lovers 1).

Having thus full y described my said improvemcnts as of my invention, I claim- 1. In a sheet-delivery for a cylinder printing-press, in combination with the impressioncylinder, a series of stripper-fingers, as S and a series of conveying-tapes, as g", each series constructed, relatively arranged, and adapted to the other so that said stripper-fingers may project below the level of said tapes until the entire length of the sheet shall have been stripped from said cylinder, and thereafter said fingers project above the level of said tapes to partially arrest the further motion of the sheet, whereby said sheet may be further conveyed away from said stripperfingers by any suitable means and at any desired velocity without contact with said tapes, substantially as and for the purposes set forth.

2. In a sheet-delivery for a cylinder print ing-press, in combination with the impression-cylinder, a series of movable stripperfingers, as S, a series of conveying-tapes, as f, and mechanism, substantially as described, for projecting said fingers below the level of the tapes while said tapes are receiving the sheet from said cylinder, and for projecting said fingers above the level of the tapes after said tapes have received the entire sheet from said cylinder, substantially as and for the purposes set forth.

3. In a sheet-delivery for a cylinder print ing-press, in combination with the impression-cylinder, a series of stripper-fingers, as

S a series of conveying-tapes, as g, eachseries constructed, relatively arranged, and adapted to the other so that said fingers may project below thelevel of the tapes while said tapes are receiving the sheet from said cylinder and above the level of said tapes after the entire sheet has left said cylinder, a series of said receiving-board, substantially as and for the purposes set forth.

4. In a sheet-delivery for a cylinder print ing-prcss, in combination with the impression-cylinder, a series of stripper-fingers, as S aseries of conveying-tapes, as 9 each series constructed, relatively arranged, and adapted to the other so that said fingers shall project below the level of the tapes while said tapes are receiving the sheet from the impression-cylinder and above the level of said tapes after the entire sheet has left said cylinder, a series of traveling forked sheet-stops, as d, and a series of traveling grippers, as d, where by the sheet is received from the impressioncylinder upon and conveyed by said tapes until entirely stripped from said cylinder, and then partially arrested by frictional contact with the stripper-fingers, the exact position of the sheet being limited by said forked sh eetstops to determine the amountof gripper hold to be taken by the grippers, and being then drawn off from said fingers by a slow and easy motion of said grippers without contact with the tapes, substantially as and for the purposes set forth.

5. In a sheet-delivery for a cylinder printing-press, in combination with the impression-cylinder, and mechanism, substantially as described, for stripping the sheet from said cylinder, a series of traveling grippers, as d, for seizing the sheets as stripped or delivered from said cylinder, and a parallelmotion mechanism consisting, substantially, of apair of" sliding radiuslcvers, as D, carrying said grippers 011 their free ends and articulated to a second pair of radius-levers, as R BF, oscillating upon a fixed axis, as R, and operated by any suitable moving part of the machine, whereby said grippers are caused to move in an approximately-rectilinear or slightly-curved path, as desired, substantially as and for the purposes set forth.
